“CSLB license verification is non-negotiable before signing any construction contract in California. Go to CSLB.ca.gov, search by license number, and verify: the license is current and active, the license type matches the scope of work (B-General, C-specialty trade), the insurance and bonding are current, and there are no disciplinary actions. Takes 5 minutes. Do it every time.”

Pro Tip

Request a payment bond on any project over $50,000. A payment bond ensures that subcontractors and material suppliers are paid even if the general contractor defaults. Without a payment bond, you can be required to pay twice for the same work if the GC fails to pay their subs. Payment bonds cost 1–2% of the contract amount — the cheapest insurance available.

Frequently Asked Questions

+How do I report an unlicensed contractor in Los Angeles?

File a complaint with CSLB at cslb.ca.gov/consumers or call (800) 321-2752. You can also file with the LA District Attorney's office for fraud. Unlicensed contracting in California is a misdemeanor with fines up to $15,000 and jail time. Document everything including texts, payments, and photos of incomplete or defective work.

+Is it illegal to hire an unlicensed contractor in California?

Operating as an unlicensed contractor is illegal in California for jobs over $500. As a homeowner, you face significant risks: no CSLB bond protection, no warranty enforcement, potential liability for worker injuries, and your homeowner's insurance may deny claims. You also lose access to CSLB dispute resolution and the Contractors Recovery Fund.

+What is the biggest contractor scam in LA?

The most common contractor scam in LA involves collecting a large deposit, performing minimal or no work, then becoming unreachable. After wildfires and earthquakes, door-to-door solicitors offering discount repairs are especially prevalent. Always verify CSLB licensing, never pay more than 10% or $1,000 deposit, and get everything in writing.

+Should a contractor pull permits or should I?

The licensed contractor should pull all LADBS permits. When a homeowner pulls permits as the owner-builder, they assume liability for code compliance, worker safety, and warranty obligations. If a contractor asks you to pull permits, it usually means they lack proper licensing. A legitimate GC handles all permitting as part of the contract.

+Can I get my money back from a bad contractor in California?

Options include: filing a CSLB complaint (they can order restitution or revoke the license), small claims court for amounts under $12,500, civil court for larger amounts, or claiming against the CSLB Contractors Recovery Fund (up to $25,000 per claimant). Document all payments, communications, and defective work with photos and timestamps.
